Application filed February 24, 1921. Serial No. 447,415. Y

My invention relates to tractor `drawn agricultural machinery and lmoreparticularly to harvesters, and has for its object the location of theadjusting devices of ka harvester in such proximity to an operator ofthe combined machines as to make the desired adjustments with ease andefficiency. Referring to the drawings in which similar. numeralsindicate identical parts-k Figure 1 is a side elevation, taken from thestubbleward side illustrating the applicaltionof my improvement, as muchof a harvester and tractor being shown as thought necessary. n l

Figure 2 is an enlarged detail view,'1n perspective, taken from thestubblewardside, showing the mounting of the various levers. Figure 3 isa similar view taken from the grainward side, and

Figure 4 is a sectional detail on the line 44 of Figure 3. y

The part of the harvester and binder shown comprises the front frame bar1, a`

transverse f frame bar 2, the stubbleward frame bar 3, shown only inFigure 1, the bull-wheel '4, a side 5 of the elevator frame with bracebars6` and 7 ,and the binder deck 8;` to the lower part of the elevatorside 5 is rigidly secured a vertical bar 9 to which is bolted a bar 10extending stubbleward and bolted to the side 5 and the bar 7.- On theupper .endof the bar 9 is mounted a casting 11 to which is secured aseat bar 12 of the ordinary type. On the brace bar 7 is bolted a casting13 having a bearing in alinement with a bearing in the casting 11 inwhich is secured a shaft 14 having rockably mounted thereon the lowerreel standard 15 carrying on its upper end the standard 16 on which thereel 17- is rotatably supported. The standard 16 is rockably supportedon a shaft 18 onthe upper end of the standard 15, and loosely journaledon the shaft 18 is a sprocket 19 integral with a larger sprocket 20. Asprocket 21 is mounted on the shaft 11 and from the sprocket 21 a chain22 leads over the sprocket 20, and a similar chain 23 leads over thesprocket 19 to a sprocket 24 on the reel shaft. The reel visoperated ina well knownl manner by power from the bull `wheel 4 through a train ofgearing mounted on the machine, which together with `the `:partsheretofore enumerated are to be found on modern binders and to which Imake no claim. f f

. A draft beamcomposed of bars .25 and 26,

is pivotally connected to a goose neck 27,

rigidly secured to the frame bar 2, and to a casting28 bolted to thevertical bar 9; the bars 25 and 26 are spaced apart and convergeforwardly, andto their forward ends issecured a hook 29 to engage withthe rear of tractor 30. To add to the rigidity of the structure of thedraft beam I provide braces 31, 32 and 33, which are bolted to the bars25 and 26 and between them. Pivotally connected to the gooseneck 27is aforwardly ex:y tending lever 34 provided with the usual type of latch toengage with a vertically dis posed curved rack bar 35 mounted on the bar25 ofthe draft beamand held rigidly in place by braces 36 and 37 whichare secured to the upper end of the rack bar 35 and to the bar 25 of thedraft beam.

n Bolted tothe upper end of the brace bar 7 1s a forwardly extending bar38, which is substantially horizontal for part of its length and 1s thenbent downwardly tothe lever 34, to which it is secured, forming with thelever 34 a forwardly extending verticallydisposed rigidfraine mounted ont-he harvester, and it is readily apparent that by reason of thisconstruction the operation of theleve'r 34 will tilt the harvester tocut'high `or low as may be desired. `When the reel 17 iscontrolled rfromthedrivers seat 39, it isby operation of aV lever 40 pivotally mountedon the seat bar 12, a rod 41 connecting the lever 40 with the standard16 and anotched sector 42, secured on the seat bar 12,` with which alatch on the lever is adapted to engage ac.

cording to the adjustment made; when shifting the control of the reelfrom the harvester f on a notched sector 46, the latter being rigidlysecured tothe bar 38 atthe bend thereof. The lever 45 is bent upwardlyin opposite directions from its pivot, the kforward part 46a extendingto convenient reach of the seat y47k of the tractor operator andcarrying a latch to engage with the notches in the sector 46 whereby thereel can be held in the desired forwardly ory rearwardly adjustedposition. The rearward part 48 of the lever Cil 45 is connected to thelever 40, by a rod 49, and as the lever 40 is connected to the reelstandard 16 by the rod L11 the foruardly or rearwardly adjustment vofthe reel 17 by operation of the lever't is apparent, the lever 40 beingfree to move, the latch thereof being held out of engagementwith therespective sector 42.

rb'ide by side With the' sector 46, and se cured on the bar 38, isa'notched'sector 50 witlrwhich alever 5ly cooperates, the latter being.pivotally supported intern'iediate its ends on the pivot-of the leverand bent to extend divergingly forward 'from its pivot; the upper part52 extending to convenient reach from the seat- 47, and provided with alatch, as usual, to engage With the notched sector 5U r1`o the lovcerpart 53 of the lever 51 is vconnected a-linkd which extends to pivotalconnection with theapex of an inverted triadic arrangement of rods 55,-56 and 57. Therod 57 is pivotally connected to a projection on thestandard 15, adjacent the sprocket 21; a lower horizontal portion of therod is pivotally connected to the lshaft 18 outside of the sprocket 20,and the rod 56 is pivotally connected to 1an eye 58 on the rearv of anupper horizontal v portion of the standard 15; by' the arrangement ofthe parts just described the rocking movement ofthe lever 51 Will swingthe standards 15 and 16 to raise or lower the reel 17.

In all horizontal binding mechanisms the deck of the bin-der islaterally adjustable by means on the harvester operated by the driver oftheyharvester, and for a similar purpose I provide thekfollowingdescribed mechanism operatively mounted convenient to the operator of atractor. Rigidly secured to the bar 38 andthe lever 34;, onthestubblewardside thereof, is a brace 59 to which is bolted astubbleWar-dly extending bracket 60 on which is mounted a notched sector61 also bolted to the lever; co-operating with the sector `61 is aclever62 pivotally supported on the bracket and provided with notches inthesector to holdV the lever in any position of adjustment. Y

,A brace 63 is connected to the bracket 6G y,and to the bar 6, and asimilarV brace Gtis ,connected to thebracket 60iand to the bar 7.

VSecured to the lever `62 above the sector 61 are links 65 and 66 whichconverge to conv nection with a rod 67 having its opposite endApivotally connected to the binder deck 8, and

.as thelatter is mounted on the harvester. in

a manner vvell known in the art, for forward o1'. rearward adjustment,it is evidentthat such adjustment as may be desired is readily effectedby operation.- of the lever 62 which is Within convenient reachfrom theseat 47 on the tracto-r.

- Rotatably journaled in thevcastings 11 and 13 is ashaft 68 A,to whichis rigidly secured a lever 69 having a latch to engage-With a notchedsector 70 loosely mountedon the shaft 68 and secured to the seat bar 12in any suitable manner. The opposite end of the shaft 68 has a forwardlyprojecting arm 69, preferablyintegral therewith', 'andr tothe foiwvard'end of which are' pivotally connected parallel links 71 and 72 havingtheir lower ends pivotallysecured to a bar 73 pivoted onv kthe brace 37and extending rearwardly. il coiled relief spring 7l has one end engagedwith a perforation in the rearvfard end of the bar 73 and the oppositeend hooked in an eye 75 on the brace bar 7. The coiistruction justdescribed is for the purpose of balancing the harvester by operation ofthe lever 65) to increase or reduce the tension of the spring 7st, forif the operator is on the harvester he will rock the lever 69 upwardlyand by the link connection of the lever with the bar 73, the latter isswung downwardly, on its pivot on thebrace 37, expanding the spring 7luntil the harvester is proporly balanced, the balance being maintainedby the latch on the lever 69 engaging with a vnotch on the sector 70.If, however, the

operator decides to change his position to the tractor, after dismountmgfrom the harvester, he will rock the lever 69 dovf'nivardly,-

consequently the bar lo will be swung upwardly reducing' the tension Ofthe spring 74 to balance the harvester againstthe loss of the vveight ofthe operator. From the construction and operation of the parts as shownand described but one man is required to operate the tractor andharvestelgfthe levers for the desired adjustments being convenient tothe seat 47.
